Fractional ownership models like those employed by Ballestra work upon the basic principle that things you don't use all the time are worth splitting costs over.

The concept was first introduced to the field of luxury travel in the 1980's by forward-thinking firms such as Netjets, who brought together buyers to purchase private jets using a time-share-like model.

Today, internet savvy companies such as Flyvictor have constructed their own market-based version of the fractional ownership model.

"We're helping the industry to become more efficient by allowing owners to charter their aircraft through the victor platform and allowing people who want to charter a jet -- not own a jet -- and take all the benefits of flying private to and from destinations," explained Flyvictor founder, Clive Jackson.

Flyvictor's website acts as a forum where owners or co-owners can advertise their jets for charter or hire. Those looking to fly solo or band together with fellow travelers meanwhile can browse to see what's on offer.

Customers are never guaranteed to get exactly what they are after but if they're lucky they may be able to pick up a bargain.

"Everyone likes to do deals, particularly the ultra high-net-worths, so if they can find an empty aircraft flying back for $50,000 dollars then why not, and if they can't they'll book a full fare aircraft," said Jackson.

These same principles of savings and efficiency are at the core of yachting company, Monocle, which aims to bring fractional ownership to the high seas.

According to Monocle president, Loren Simkowitz, sharing guarantees the benefits of ownership without the hassle and expense of full management.

"It's the high cost ... that drives people out of yachting," he said. "Most people use (a yacht they purchase) three to four weeks a year. The rest of the time it sits around as an idle asset depreciating. You spend more time managing the boat than your business," he added.

With an increasing number of high-net-worth individuals looking to save money where they can, Simkowitz believes those opting for fractional ownership plans will only increase in the coming years.

"I think it's the wave of the future," he continued. "People are much more fiscally prudent with their money. People don't want to be tied down to an asset they use infrequently. They're smarter than they were in 2000," he added.
